THIRD_GENERATION

 

THIRD GENERATION OF COMPUTER (1965-1974)

      The third generation computer were developed during 1965 AD to 1974 AD.They used integrated circuit (IC) as electronic circuit.IC circuit consists of a large number of electronic components placed on a single silicion chip by a photolithography process.Integrated Circuit was developed by an engineer Jack Kilby in 1958.

This new technology (IC) made the third generation computer more reliable faster,smaller,easier to operate,high capacity,less expensive than previous generation computer .Third generation computer included the use of an operating system for automatic processing and multi programming.

 

Feautures of third generation computer are:-

·        They used Integrated Circuits(IC) as electronic circuits

·        They used semiconductor device as primary storage.

·        They had large storage capacity.

·        Their operating speed was improved to nano-second.

·        They were more reliable,much smaller in size,easier to operate and less expensive than previous generation computers.

·        They included multi programming,batch and time-sharing operation system.

·        They extensively used high level programming language including Report Programming Generator(RPG) and Pascal
